APPARATUS FOR MAKlNG LAMiNATED BELTS,

ShECIFICATION forming part of Letters Patent No, 358,808, dated March 1, 1887.

Application filed July 30, ISEU. Serial No. 209,603. (No model.)

.To a, whom it may concern:

Be itknown that}, Mnnnrcn (Lanny, a subject of the Queen of Great Britain, residing at New Brighton, in the county of Chester, 5 England, have invented certain new and useful Improvements in Apparatus for and Methods of Making Laminated Bolts, of which the following is a description in such full, clear, concise, and exact terms as will enable any one to skilled in the art to which lnyinvention relates to make and use the same, reference being had to the accompanying drawings, making part of this specification, and to the letters and figures of reference marked thereon. 5 Similar letters indicate correspondingparts in all the figures. l

In said drawings, Figure 1 illustrates a front elevation, partly insection, Fig. 2 a top View, and Fig. 3 a side sectional view, oimy improved apparatus. Referring to said drawings, A is a belt, consisting of several distinct plies or laminzc, each width andply being distinct and separate from all the rest, substantially such a belt as I have described and illustrated in Letters Patent granted to me November 9, 1886, No. 352,460, to which reference is here made fora fuller description of the same, this present specification being confined to a description of 0 the apparatus and method employed in man ufacturing said belt, or other belts made in substantially the same manner.

B is a table, upon which a pair of guides, (J,

are set. The distance between these guides may be varied to suit ditfercnt widths of canvas by means of the doublcthreaded screw I). A shaft, E, threaded only a part of its length,

connects with one of said guides, by means of which the position of said guides may be shiftedfrom side to side, in order to bring the proper portion of the belt under the needle N of the sewing-machine F.

,Instead of the rod E being screw-threaded only a portion of its length, I may employ a rod screw threaded throughout/ its entire length by making the hole through which it passes in one of said guides so large that it dries not engage with said screw-thread.

. Behind the sewing machine a pair of fric- 5 tion or *ri) in rollers G are laced said O b I 9 1 7 rollers being connected through the belt ll. with a suitable source of power for operating the same. By means of these rollers the belt is fed through the guides and under the machine-needle. The rod I, placed in front of the machineneedle, serves to keep the lftllllllit) hard upon each other and down against the table when they are operated upon by the needle.

J J area pair of nippers, placed in front of the needle to press the belt down against the table, and, in connection with the feedingrollers G G, subject the belt to tension as t passes under the needle." These nippcrs are raised and lowered by means of the screws In K, preferably geared together to act in unison, as shown in Fig. 1.

At the forward end of the guide-box C O is a system of parallel rods, L L. lhe number of. these rods eorrespondswith the numberof plies of material which are employed to make up the necessary thickness of the belt. They are placed asuiiicient distance apart to permit a single thickness of the material to pass between them. Theoiiice ofthese rods, 7 5

is twofold. In the first place, they prevent friction between the several plies, which would interfere with the action of the guides in brlnging each ply home to its proper position with relation to the other plies, and, in thesecond place, they prevent the crimping or wrinkling of the several plies and remove such crimps or wrinkles, ifany be present. By the devices I have described each ply is separately adjusted by the guides, so that they lie or actly on top of each other and make rt-belt 111 which the edges lie in the same h rizontal plane, are smooth and even, and capable of running smoothly through and resisting the wear of guide-forks.

In the Letters Patent above referred to l have described a belt made of a plurality of plies of cotton,canvas,or duck, each ply woven to the exact width it is desired ,to make the belt, each width and ply being separate and distinct from all the rest and having a sclvage on each edge thereof. These several plies, piled one on the other llatwise, are stitched together longitudinally by rows of stitching throughout the entire width of the belt and close along each edge, by which means the hard selvage edges of the several plies are drawn hard upon each other, thus making the two edges of the belt to consist of thc'combi- IOO hard upon, each other by rows of stitching To accomplish thisalong the 'extremeedges. result is the principal object of my present invention. The guides which I have described .not only bring the plies into the proper position with relation to each other, but they hold them there while the belt is being stitched.

- In stitching the belt, it only one machine be used, I'prefer to stitch a seam down the middle of the belt and then add parallel rows of stitching-say about three-eighths of an inch apart-commencing from the middle seam and running out toward each edge. If two. machines be used, I prefer to put the first seams along the two extreme edges of the belt and V v afterward add the intervening seams.

I have described the best way of making my belt, and I understand that any merely formal change in the method and materials used and in the apparatus and devices em-- rods, substantially as set forth. I

'7. In the manufacture of laminated bel composed of separate plies, the method, sub- 75- ployed will be covered by this description.

I therefore claim and desire to secure by Letters Patent- 1. In a machine for manufacturing lami nated belting consisting of separate and dis-' tinetlaminae, a sewing-machine, in combina tion with feeding mechanism, and a guide having sides adapted to be set apart a distance equal to the width of the belt, for the purpose of adj usting the edges of the several laminae exactly upon the same vertical plane and holding them there while being stitched, all arranged to operate substantially as de scribed.

2. In a machine for manufacturing laminated belts composed ofseparate plies, a sewing-maehine, combined with feeding mechan- K ism, and a guide-box having parallel sides, and means, substantially as described, or adjusting the distance betweensaid sides.

3. In amachine for manufacturing ami- 5o nated belts composed of separate plies, the com-' binatiou' of feeding mechanism and guides,and means, substantially as described, for holding the several plies apart as they approach said guides. p

4. In the manufacture of laminated belts composed of separate plies, the combination of feeding mechanism and guides, and a plurality of parallel rods set in a frame in front of said guides, for holding the several plies apart and 6c removing the wrinkles therefrom as theyap-' proach said guides, substantially as described.

, 5. In the manufacture of laminated belts I composed of separate'plies, the combination of a sewing-machine, feeding-rollers, guides,

to operate substantially as and for the purpose set forth. a v

6. In the manufacture of laminated belts composed of separate plies, the combination of a sewing-machine, feeding-rollers, guides, tension-nippers,-and a plurality of parallel stautially herein described, of adjusting the relative position of said plies, which consists of separating the several plies from each other and of feeding the plies so separated between guides.
